浅析GB 150.1—2011附录B《超压泄放装置》

Analysis on “the Excessive Pressure Relief Devices” of GB 150.1—2011 Appendix B

对GB 150附录B前后两个版本(1998版和2011版)从超压限度、动作压力、泄放面积计算三个方面进行了比较分析。通过对附录B压力容器超压限度相关规定的分析,根据超压原因及所设置的超压泄放装置的不同归纳出了8种超压事故工况,并给出了各工况下超压泄放装置动作压力及泄放面积确定原则,为设计人员选择超压泄放装置提供依据。

This paper make comparative analysis between edition 1998 and GB 150.1-2011 appendix B from excessive pressure limit, set pressure and the calculation of vent area. Through analyzing the requirements of excessive pressure limit in appendix B for the pressure vessels, this paper included eight kinds of operating conditions for the excessive pressure contingencies accordifig to the reasons of excessive pressure and differences of the pressure relief devices, and presented the determining principles of the set pressure and vent area under different operating conditions, which provided basis for the designers to select pressure relief devices.
